What to expect on Little Si Trail Viewpoint – Mount Si Viewpoint loop from North Bend
The journey begins on the Little Si Trail, where you'll immediately encounter a steep incline and switchbacks before it levels out through lush, verdant forests. Consider integrating the Boulder Garden Loop, a peaceful but challenging section winding through massive moss-covered boulders and towering conifers. As you ascend towards Mount Si, particularly on the Old Mount Si Trail, the terrain becomes significantly rougher and steeper, demanding considerable effort. Your reward comes with breathtaking panoramic views from Little Si's summit, encompassing the Snoqualmie Valley and surrounding peaks, expanding further towards the Cascade Range as you climb Mount Si. This route is definitely for those seeking a strenuous challenge and diverse scenery.
Planning your visit
Both Little Si and Mount Si are highly popular hiking destinations near Seattle, with the Little Si trailhead serving as a starting point for various routes. The trails are accessible year-round and generally well-maintained, though combining them into this extensive loop is a significant undertaking requiring good physical conditioning. Be prepared for a long day on the trail, and ensure you have ample water and supplies. Parking at the Little Si trailhead can fill up quickly, especially on weekends, so an early start is advisable.
